1 Claim. (Cl. 160-91) This invention relates to improvements incombination screen and storm sash frames.

lt is the object of the present invention to provide a unitarilyassembled combination storm and screen sash for removable application toa conventional window frame havingdouble hung windows. ln the device ofmy invention the combination sash frame is of simple and inexpensiveconstruction and all elements thereof are mounted for unitary handling.ln the specic embodiment of my invention shown in the drawing thecombination storm and screen sash has fixed glass and screen sashelements permanently mounted in the frame, and the frame has a way oisetlaterally from the plane of the lixed sash with a movable storm sashslidable in said way to selectively expose and block said screen.

The invention also relates to the specific structure of the sliding sashway by which the Sliding sash is readily removed from engagement withsaid way. ln the preferred embodiment of the invention the sash waychannel at one side of the xed storm sash element is relieved to permitlateral disengagement of the sliding sash from the way.

A further object of the invention is to provide means for readilymounting the combination storm and screen sash frame with respect to thesill and lintel of a conventional window frame. in the device of myinvention a releasable latch connects the top rail of the sash framewith the lintel of the window frame, the bottom rail of the sash frameand the sill of the window frame being provided with interengaging riband channel interlock means.

Other objects and advantages of the invention will be more apparent toone skilled in the art upon examination of the following disclosure` Inthe drawings:

Fig. l is a front elevation of my combination screen and storm sashframe.

Fig. 2 is a vertical cross section taken through my novel storm andscreen sash frame mounted in a conventional window frame.

Fig. 3 is a cross sectional view taken along the line 3-3 or" Fig. 1,the sliding storm sash being partly removed from its way.

Fig. 4 is an enlarged fragmentary cross sectional lView taken along theline 4 4 of Fig. l.

Fig. 5 is a fragmentary cross sectional view taken along the line 5-5 ofFig. 1.

A conventional window frame comprising a sill 19 and lintel 11 andhaving conventional double hung sash 12 and 13 is shown in Fig. 2.

My novel combination screen and storm sash frame comprises upper rail14, lower rail 15, intermediate rail 16 and side Stiles 17, 22. Theupper and lower sash frame lights are defined by a rabbeted upper seat18 for the glass 19, and a rabbeted lower seat 20 for the screen 21. Theglass 19 and screen 21 are permanently fixed within their seats by meansof the molding strips indicated generally by reference character 24.

Thus far I have described a conventional double light storm windowstructure, in which the lower glass has been replaced by the screen 2l,however, in the device of my invention the upper and lower rails 14, 15and side stiles 17, 22 of the frame are of conventional storm windowthickness (DAW). The intermediate rail 16, however, is about one halfthat thickness, or about S.

The rabbeted seats 1S and 20 for the glass 19 and screen 21 are disposednear the outside face of the sash frame. Near the inside face of thesash frame l provide a seat 25 rabbeted in the top and bottom rails 14,15 and side stiles 17, 2?.. Side stile 22 is provided with an inwardlyfacing channel Way 26 which tits into seat 25 and which extends fullybetween top and bottom rails 14, 15. Side stile 17, however, is providedwith an inwardly facing channel way 27 which tits into seat 25 butextends only between the bottom rail 15 and intermediate rail 16.

Accordingly, while the lower light occupied by screen 21 has channelways 26, 27 along both stiles of the sash frame the light occupied byglass 19 has channel 26 at one side only, the other side being laterallyopen. Accordingly, a separate storm sash includingglass 28, top andbottom rails 29 and 3@ and side stiles 31, 32 may be manipulatedlaterally through the said opening (as suggested in Fig. 3) to engageits stile 32 with the upper half of channel 26.

Channel 2d provides a fulcrum in which the stile 32 of the sash pivotsin the direction of the arrow 33 for removal of the sliding sash of theframe and in the reverse direction of the arrow 33 to insert the slidingsash in the frame. Stile 31 of the sliding sash is thus received in theportion of rabbeted seat 25 which extends above channel way 27. Fromthis position over the light occupied by glass i9 the sliding sash maybe slid downwardly in the ways 25, 27 to intermediate positions and theextreme position shown in Figs. l and 2 in which the glass 23 blocks thelight occupied by screen 21.

As best shown in Fig. 5 lower rail 30 of the sliding sash may beprovided with a detent pin 36 biased by compression spring 37 to projectthe pin 36 through hole 38 in side stile 31 and beyond said side stilethrough the hole 39 in the base web of channel 27 to enter aligned hole40 bored into the sash frame stile 17. Pin 36 carries an operator handle43 and knob 45. The handle 43 slides in slot 44 formed in the rail 30.Engagement of handle 43 with the edge of slot d4 limits the projectionof pin 36 into the hole 4d.

The stile 17 may be provided with additional vertically spaced laterallyextending holes 46, 47 with which pin 36 may be engaged in successivepositions of the movable sash. The mechanism at the other side of lowerrail 31 is the same as just described and is given the same referencecharacters in the drawing.

In its uppermost position pins 36 may engage the uppermost set of holes47. Even though the side stile 31 of the movable sash is no longerconfined by channel way 27, engagement of pin 36 in hole 47 willrestrain the sash against lateral removal from its way. However, whenpin 36 is retracted against the bias of spring 37 the movable sash maybe pivoted in the manner shown in Fig. 3 for complete removal thereof.

Upper rail 29 of the movable sash receives the glass 2S within itschannel flanges which also clamp the side margin of a weather strip 43having a portion 49 curled about a ilange of the top rail to dispose thestrip between the rail 29 and the intermediate rail 16 of the sash framefor weatherproong. he weatherstrip 43 is of natural or synthetic rubberor other resilient material.

It will be noted that intermediate rail 15 is relieved to provide abevel at Sti extending across the lower half atented Feb. 12, 1957 3 ofthe rail from the way on one side to the way on the other to'ss'ue aperfect weather seal when the weather strip is inV closed position. 'A iThe movable sash is also provided in its lower rail 30 with a hand grip52 by which it may be moved from one position to another.

Sill 10 is provided with a step 53 and shoulder 54 against which thelower rail 15 of the sash framey may be seated in the course of mountingthe frame in the window opening. The lower edge of bottom rail 15` maybe grooved'at 55 for interlocking engagement with the upstandin'g rib 56mounted on the step 53.

kThe lintel 11 may be provided with a latch bracket 57 releas'ablyengaged by the rotatable latch 58 mounted by screw 59 on upper rail 14of the sash frame. The latch 58 has a handle 62 and a relieved portion63 opposite the handle and through Vwhich the latch lug 57 passes in thecourse of applying the sash frame to the window. Latch 58 is thenrotated by means of the handle to engagement with the lug to maintainthe sash in position.

To 'manipulate latch 58 upper sash 12 of the double hung window isdesirably lowered to provide a space through which the installers handsmay reach Vthe latch. By disposing the latch at the uppermost part ofthe sash it is out Vof the reach of children for safety purposes.
